Explore our premium factory-direct rubber and polymer conveyor belts manufactured to rigorous ISO, DIN, and RMA international specifications.
In the design of modern material handling equipment, compound hardness represents the foundational specification dictating conveyor belt utility, surface wear dynamics, and power loss index. A Shore A hardness rating of exactly 60 Shore A indicates a high-performance elastomeric composition that balances elasticity and tensile stiffness. Chemically optimized utilizing a precise ratio of natural rubber (NR), styrene-butadiene rubber (SBR), and butadiene rubber (BR), 60 Shore A formulations provide the ideal mechanical impedance match for medium-density bulk solids handling.
Unlike harder rubber formulations (e.g., Shore 70 A or 80 A), 60 Shore A elastomer matrices exhibit a lower dynamic storage modulus (E') while maintaining exceptional loss modulus (E") controls. This structural combination yields excellent damping characteristics, minimizing impact-induced microfractures in the inner textile reinforcements (such as EP or NN fibers) during vertical dump loads. Furthermore, a 60 Shore A compound provides a highly favorable friction coefficient against steel drive pulleys, limiting slip risk and optimizing traction without increasing cover wear.
How technical innovations and sustainability imperatives are redefining heavy-duty bulk handling infrastructure globally.
Global demand is rapidly shifting toward Low Rolling Resistance (LRR) conveyor belting. By refining the viscoelastic properties of 60 Shore A rubber, manufacturers reduce the indentation energy losses caused by rollers, decreasing system power consumption by up to 15%.
Modern conveyor belts now feature embedded RFID chips and magnetic sensor loops. This technology enables real-time monitoring of wear patterns and internal ply separation, preventing catastrophic field failures in automated logistics lines.
Mining operations in South America and Australia require extreme abrasion resistance. Incorporating nanosilica and functionalized carbon blacks into 60 Shore A rubber provides excellent durability, extending operational life cycles in heavy iron ore and coal applications.

A multi-tiered manufacturing quality management paradigm ensuring high industrial performance in severe environments.
We host an independent chemical analysis room and physics laboratory. This guarantees immediate, real-time testing of rubber compounds, reinforcing yarns, and vulcanization output from raw materials to final packaging. Non-conforming materials are strictly prohibited from entering production.
Our dedicated quality inspectors utilize sophisticated testing equipment—including moving die rheometers, electronic tensile testers, and DIN abrasion testing drums. This structured process guarantees the physical and dimensional accuracy of our products.
Backed by strong engineering capability and a comprehensive field support system, our systems are widely utilized across mining, steel, metallurgy, energy generation, chemical fertilizer, grain storage, and port transport operations nationwide.
Hebei Boao Rubber Technology Co., Ltd. utilizes advanced manufacturing standards to optimize supply chain resilience for international heavy industries. Operating within the Boye County Industrial Park in Hebei Province, our facility uses local industrial clusters to secure stable raw material supplies, reliable energy reserves, and efficient transport channels to major sea terminals like Tianjin Port. This strategic position minimizes procurement overhead and transit times.
Under our Factory 4.0 roadmap, we have updated our mixing, calendering, and vulcanization lines with electronic control networks. These automated systems control temperature profiles within ±1°C during the rubber curing cycle, ensuring uniform physical properties across large manufacturing batches. By combining automated production with strict laboratory testing, we balance competitive pricing with reliable quality control.
All conveyor belts are designed to comply with DIN 22102 (Germany), AS 1332 (Australia), RMA (USA), and JIS K 6322 (Japan) standards.
Raw rubber and reinforcing plies undergo batch testing to verify chemical composition, tensile strength, and aging properties.
Our modular calendering and vulcanizing lines support rapid setups, allowing for custom widths, thicknesses, and cover designs.

Common engineering and procurement questions regarding 60 Shore A conveyor belts answered by our technical department.
A hardness of 60 Shore A provides a balanced mix of elasticity and structural strength. It is flexible enough to absorb impact energy from falling rock or coal, reducing fabric ply damage. At the same time, it maintains sufficient surface resistance to prevent premature micro-abrasion from sharp particles during high-speed transport.
EP (polyester warp, polyamide weft) plies have a high tensile modulus and low operational stretch, making them suitable for long-distance conveyor runs. NN (nylon-nylon) plies provide higher elasticity and superior impact resilience, which makes them ideal for short-to-medium systems with high impact forces or tight bending configurations.
Standard rubber compounds will stiffen in sub-zero environments, which increases the risk of cover cracking. For extreme temperatures, we offer customized cold-resistant compounds. These modify the rubber matrix to maintain elasticity and prevent crack propagation down to -40°C or -50°C.
We source raw materials from verified, high-grade rubber and textile suppliers. Our chemical laboratory tests every raw batch before vulcanization. Automated mixing and curing lines maintain precise control parameters, and final physical properties are verified and documented before shipping.
LRR compounds minimize the energy absorbed as the belt deforms over conveyor rollers. Utilizing a specialized 60 Shore A formulation can lower indentation energy losses, reducing drive motor electricity consumption by 8% to 15% depending on system layout and load.
Hot vulcanization is the preferred splicing method for high-tension systems. This process uses matching uncured tie gum and cover rubber cured under heat and pressure, achieving up to 90% of the belt's original tensile strength. For low-tension lines or rapid maintenance, cold bonding agents can be used.
